Site description Gibbs Island is a small island (21.8 km2) located ~25 km to the southwest of Elephant Island, bordered to the north by the Loper Channel and to the south by the Bransfield Strait. A thin section of land, known as The Spit, joins Furse Peninsula in the east to the main part of Gibbs Island in the west. This IBA comprises Furse Peninsula at the eastern extremity of Gibbs Island, The Spit and a small ice-free area on Gibbs Island west of The Spit.
A range of lichens, mosses, algae and liverworts have been recorded on Gibbs Island. On the south coast of the island, ~800 m west of The Spit, moss communities grow at altitudes of ~100 m (Allison & Smith 1973). Mosses, lichens and algae are also found at the eastern extremity of Gibbs Island growing at elevations of 250 – 300 m. (Lindsay, 1969 in Allison & Smith, 1973).
No long-term meteorological records exist for Gibbs Island. However, meteorological observations made in the Elephant Island group between 10 Dec 1970 and 26 March 1971 show the mean daily temperature was 1.4° C with minimum and maximum temperatures of below – 5° C and 15° C respectively (Allison and Smith, 1973). Cloud cover and precipitation were frequent, with over 415 mm falling as snow or rain over the 107 days, and a mean wind speed for the survey period of 7.2 ms-1 (ibid.).
